Low-Peak™ time-delay, rejection-type fuses
## **LP-CC Class CC**
## **Specifications:**
**Description:** Time-delay, current-limiting, rejection-type fuse – 12 seconds (minimum) at 200% rated amps.
**Dimensions:**[13] ⁄32˝ x 1[1] ⁄2˝ (10.3 x 38.1mm).
## **Ratings:**
Volts — 600Vac (or less)
- 300Vdc ([1] ⁄2-2[1] ⁄2A and 20-30A)
- 150Vdc (2[8] ⁄10-15A)
Amps —[1] ⁄2-30A
IR — 200kA RMS Sym.
— 20kA DC
**Agency information:** CE, Std. 248-4, Class CC, UL Listed, Guide JDDZ, File E4273, CSA Certified; Class 1422-02, File 53787, RoHS compliant (15-30A).
## **Features and benefits:**
- Time-delay coupled with Class CC current-limiting response provides close sizing on small motor and relay circuits, and maximum component short-circuit current rating protection.
- 200kA interrupting rating provides high ratings for control circuit locations.
- Class CC rejection feature, with appropriate fuse block, prevents inserting lesser-rated supplementary fuses.
- Inventory consolidation of[13] ⁄32 x 1[1] ⁄2 inch supplementary fuses reduces SKU investment and minimizes potential for misapplying fuse.
- Selective coordination ratio of 2:1 (within Low-Peak fuse family) prevents electrical shutdowns from extending beyond the failed circuit.

Wind fast-acting CUBEFuse™ – finger-safe fuse
## **WCF 690V**
## **Features and benefits:**
- Maximize uptime and reliability using fuses designed and listed to UL 248-1.
- Minimize chances of equipment failure and personnel injury when using full range fuses having the industry’s fastest response time to low-magnitude faults.
- Maximize return on investment with fuses proven to withstand harsh temperatures.
- Minimize design time, operating outage time and replacement cost with fuses qualified in excessively changing enviromental conditions.
- Simplify compatibility with readily available industry standard holders.
## Catalog Symbol: WCF_RN
Description: Finger-safe, fast-acting CUBEFuse for wind power generation.
Electrical characteristics: Maximum clearing time at 200% rated current:
- 4 minutes for 1 to 30A fuses
- 6 minutes for 35 to 60A fuses
- Temperature derating: Designed to maximize rated capacity in elevated environmental temperatures.
- Overload protection: Proven to clear faults faster than the UL requirement.
- Power loss: Minimal energy consumption leading to increased efficiency.
- 8 minutes for 70 to 100A fuses
Ratings:
Volts — 690Vac Amps — 1-100A IR — 50kA AC (1-60A) IR — 30kA AC (70-100A)

_**Available with indication**_
## **Specifications: Description:**
Dual-element, time-delay fuse;
10 seconds (minimum) at 500% rated amps. Now available with optional indication on select ratings (see catalog numbers table).
**Dimensions:** See page 1-5 for Class J dimensions.
## **Ratings:**
Volts — 600Vac (or less)
- 300Vdc (or less)
- Amps — 1-600A IR — 300kA RMS Sym.
- 100kA DC
**Agency information:** CE, UL Listed, Guide JFHR, File E56412, CSA Certified (200k AIR) Class J per CSA-22.2 No. 248.8, Class 1422-02, File 53787, RoHS compliant.
## **Features and benefits:**
- Separate overload and short-circuit elements provide time delay for sizing of high inrush loads linked with Class J current limitation.
- Selective coordination ratio of 2:1 (within Low-Peak fuse family) prevents electrical shutdowns from extending beyond the failed circuit.
- Series combination ratings with branch circuit breakers allows broad range of coverage, independent of breaker manufacturer.
## **Typical applications:**
- Power panelboards
- Branch circuit breaker panelboard mains
- Machinery disconnects

- Quality construction, using high-grade materials, provides lower watts loss and operating temperatures with superior arc quenching during current-limiting action.
## **Typical applications:**
- Large distribution switchboards
- Power panelboards
- Large machinery disconnects

- Separate overload and short-circuit elements provide time delay for sizing as close as 125% of motor FLA.
- 2:1 selective coordination amp ratio (within the Fusetron RK5 fuse family) prevents overcurrent events from opening upstream Fusetron fuses.
- Insulated end caps for 225A-600A fuses reduces exposure to live parts and extends air gap to distance between blades of adjacent mounted fuses or to housing.

## **W**
## **SL and TL**
## **Specifications:**
**Description:** Fast-acting plug fuse.
**Dimensions:** Edison base plug. **Construction:** Brass threads with plastic body.
## **Ratings:**
Volts — 125Vac Amps —[1] ⁄2-12A
IR — 10kA RMS Sym.
**Agency information:** CE, Std. 248-11, UL Listed, Guide JEFV, File E12112.
## **Specifications**
**Description:** Time-delay, loaded link plug fuse.
**Dimensions:**
SL — Rejection base
TL — Edison base
## **Construction:**
SL — Plastic base with rejection threads
TL — Brass threads with plastic body
## **Ratings:**
Volts — 125Vac
Amps — 15-30A
## **Features and benefits:**
- Dependable, fast-acting circuit protection with 10kA interrupting rating for added safety when applied to existing plug fuse systems and 125-volt single-phase control circuits.
## **Typical applications:**
- Replacement only in existing systems.
- For general purpose circuit protection.
- Use for lighting and other non-motor circuits.

IR — 10kA RMS Sym.
**Agency information:** CE, Std. 248-11, UL Listed, Guide JEFV, File E12112.
## **Features and benefits**
- Time-delay loaded link TL Edison base plug fuses pass motor overload starting currents without opening and allow closer sizing to motor load for added protection.
- Time-delay loaded link SL fuses provide a rejection feature (when used alone or with Fustat adapters to retrofit Edison base holders) to help prevent overfusing.
## **Typical applications**
- Small motor and inductive load circuits with high in-rush current levels.
- Used with box cover units to provide equipment protection.
- Applications benefiting from fuse rejection (SL series only).

Plug fuses
## **S and T**
## **Specifications:**
**Description:** Dual-element, time-delay plug fuse.
## **Dimensions:**
S — Rejection base T — Edison base
## **Construction:**
S — Plastic base with rejection threads T — Brass threads with plastic body
## **Ratings:**
Volts — 125Vac
Amps — S:[1] ⁄4-30A
— T:[3] ⁄10-30A
IR — 10kA RMS Sym.
**Agency information:** CE, Std. 248-11, Type S and T: UL Listed (0-6[1] ⁄4) Guide JFHR, File E56412 (7-30A) Guide JEFV, File E12112; CSA Certified, Class 1423-01, File 53787.
## **Features and benefits:**
- Time-delay, dual-element T Edison base plug fuses provide small motor overload protection when used with box cover units.
- Time-delay, dual-element S plug fuses provide a rejection feature (when used alone or with Fustat adapters to retrofit Edison base holders) to prevent overfusing of branch circuits.
## **P and TC**
**Specifications: Description:**
P - Type P dual-element fuse
TC - Type D dual-element, time-delay fuse **Dimensions:** Edison base
**Construction:** Brass threads with plastic body.
**Ratings:**
Volts — 125Vac or less Amps — 15-30A IR — 10kA
**Agency information:**
P - CSA Certified
TC - CSA Certified (Class 1423-01, File # 53787)
## **Features and benefits:**
P
- “P” rating for Canadian applications.
- Non-time delay for non-inductive loads
TC
- “D” rating for Canadian applications
- Heavy duty TC fuses are industrial strength products, featuring dual-element construction.
- This spring loaded design provides superior short-circuit and overload protection.
- The TC fuses have more time-delay than the medium duty fuses in order to better protect industrial motors and residential circuits.
## **Typical applications:**
- S — residential load centers
- T — box cover units for small motor overload protection
- Applications benefiting from fuse rejection (S only)
